Chad,
I think maybe you've misunderstood the problem. I am able to delete any screen I wish. The issue was with the window telling you it's deleting,. Instead of going away after what I thought was sufficient time to do the actual delete, the window stayed there for way too long. I waited as much as 15 minutes in one case, but don't really know how long it would have remained had I left it.
So, when I grew tired of waiting, I would either log out/in or else do a role change or Display refresh; all of which cleared the screen and let me carry all. But in all cases, the screen did get deleted. It's almost as if the system forgot to send a message back to clear the screen, or at least such a message was not received. I know that sounds a little weird, but I have had that with other events, so I know it happens.
If you can't simulate the problem at your end, I doubt if it's worth pursuing.
thanks,
Rolf
